Introduction: Automatic Marshmallow Gun

This instrutable will teach you how to create an automatic marshmallow gun out of 1/2 inch pvc pipe. This is my first instructable so feel free to give me suggestions of what i could do better.

Step 1: Materials

To make this gun you will need:
2 1/2 inch pvc caps
2 1/2 inch pvc elbows
2 1/2 inch pvc tees
4 5-inch sections of 1/2 inch pvc pipe
1 11 inch pvc pipe (barrel)
1 8 inch pvc pipe (hopper)
1 9 inch pvc pipe (mouth piece)
cotton balls

Optional:
Electrical tape (for looks)

Step 2: Asslembling Mouthpiece

To make the mouthpiece you will need to connect the 9 inch pipe to an elbow connect that to a 5 inch section and connect that to a tee.

Step 3: Assembling Hopper

To make the hopper you will need to attach a cap to the 8 inch pipe, then on the other end attach a tee and to that attact a five inch section.

Step 4: Asslembling Handle

To make the handle you will need to attach 2 5ive inch pieces to an elbow and put a cap on one of them. The piece without the cap needs to be suffed with cotton balls. The other piece shall remain hollow so you can fill it with marshmellows (can not hold very many but why not?)

Step 5: Put It All Together

In this step we will put all pieces together and attach barrel.

Step 6: If There Was Any Confusion

Just in case you didnt understand anything here is a more detailed picture if everything.

Step 7: Usage

In order to use this gun you first need to load the hopper (8 inch pipe) with mini malshmallows (mine held 15). Then you need to reattach to gun, aim in a safe direction, and blow continuisly through mouthpiece. If all went well all 15 marshmellows should have left the barrel. Mine shoots a good 20 yards.

Step 8: Modification

There are many improvements that can be done to this gun. I wrapped electric tape around mine to give it a better apperance. You could also put another tee, behind the hopper, facing down and attach another handle. You could ajust the lenght of the pipes for a bigger or smaller gun. There are an infinate amount of possibilites.

Step 9: Ammunition

This gun is designed to shoot miniature marshmallows I would put a picture of the kind I use, but they are all gone.

I made a few of these. They also shoot some brands of dry dog food, so I can get the dogs running around the back yard chasing treats for exercise.

replace L joint at the back with a T joint, then add a piece of pipe about a foot long, after that place the old L joint at the back along with a 4 inch piece of pipe going down, cap that off and you have a stock.

a good twenty yards? that's sixty feet, an I find it hard to believe you can launch marshmallows twenty yards. please load a video proving the distance then I'll believe you.

look at the physics involved. it works. the impulse of the air blowing leaves it with force for while. the longer the barrel, the longer the distance to a large extent. there are some exceptions though.

i think the marshmellows will go further if you put the hopper by the mouthpiece before the 1st bend

I've discovered a great use for old AA batteries. Put one in the hopper, and it pushes the marshmallows down just enough to keep feeding them into the barrel. Umm...be sure to put it in ON TOP OF the marshmallows.

I myself have 1/2 in. piping although a different kind of gun,(semi-auto)not that it really matters but I still can't get the marshmellows to go all the way down the hopper! What about making them skinnier or cutting them smaller? Anything else? Any advice would help, Thanks! John

let the marshmallows dry out or use mini-marshmallows. if they're dry, they wont stick together as much. and, as i said there, use cornstarch. i love the stuff for all of my marshmallow-related escapades.

I think cutting them smaller would make them stick. maybe you could put some sort of spring in the hopper to help them along.

author
chocolate_zombie made it!(author)2008-08-09

i did something like this, but with a 2-liter bottle as the hopper. try sprinkling on a little cornstarch on the inside of the gun and in the marshmallows to keep them from sticking.

STOP SPAMMING YOUR INSTRUCTABLE AROUND. I dont spam my pure pwnage modded sprinkler valve spud gun around.

Actually, he was just proving the point that someone has done it and posted it on instructables.

Nah he posted it before.. go scroll down you can see that he said "like mine"be4

hey i bet no one has thought about this. hooking up an air compresser to shoot marsh mellows

author
blugyblug made it!(author)2008-07-03

everyone does that, and they shove a modded sprinkler valve piloted by a blowgun all pressured to 120psi shooting golfballs, marbles, batteries and only occasionly marsh mellows...

OK how about making a true magizene that pushes the marsh mellow up into the barrel

author
JMB made it!(author)2007-06-05

or how about you design that and put it on here

i wold but don't have a camera when i get one i will

author
demonslayer12 made it!(author)2007-06-12

another mod you could try is take a T, make a grip, put 2 1" pieces on both sides of the T and that way you have 2 grips

I made one that you pump up with an air compressor to shoot the larger marshmallows. Much easier to fire, and you get a lot of distance:

You could also make the loading part into an attachment so it could be attached to other marshmallow guns.

sorry about what I saidearlier but how far does it shoot? Oh yeah instead of stuffing the hanle with cotton balls you could put tape on the inside, that worked well for me.

author
Dr.+Explosion made it!(author)2008-06-20

or use a nickel in the joint, fits perfect

I have built something like this before and it works really well. If u get hit at close range on bare skin, it has a good sting especially w/ stale m-mallows

i would put one of those four way PVC connector thingies at the bottom of the magazine, instead of the 3 way one, so you can put in something to hold and make it more accurate. im gonna deck out mine with a laser sighter and a scope and a stand and a squash and a....

Good job, gotta love any firearm, yes even a marshmallow one. I've seen people paint them in camo colors, and even put in CO2 tanks and a load of fancy stuff. And nice speed loader! There was another gun just like that on here though, but anyways nice instructable!

author
lollipopsalot made it!(author)2007-10-04

how could you add a co2 tank to it and can u explain it

author
bob+the+builder+%231 made it!(author)2008-06-03

yeah that would be great.

author
bob+the+builder+%231 made it!(author)2008-06-03

It can't shoot normal paintballs because it's 1/2 inch pipe, can it?

author
Rhence made it!(author)2008-05-27

so where can you find a store that sells pvc pipes?

Lowes / Home Depot or any hardware store
